Referring now more particularly to the accompanying drawings, wherein like and corresponding parts are designated by similar reference characters. A generally designates the tubular handle having a straight attaching end portion 1 from which extends angular portion 2, straight medial portion 3, a second angular portion 4 and straight end portion 5 in line with end portion 1, medial portion 3 being parallel to end portions 1 and 5.

End portion 5 has an annular peripherial head 6 and an internally threaded open end 7. A bolt 8 has a threaded shank 9 in threaded engagement with end 7 for closing said end and an air vent 8a therethrough.

IA knob 10 is rotatably and slidably mounted on end portion 5 of said handle abutting bead 6 and has an enlarged annular bore 11 larger than the head of bolt 8 and an intermediate rotatably mounted on medial portion 3 can be held in the users other hand.

Handle A has a tubular extension 15 to end portion 1 and as best shown in FIG. 10, a sleeve 16, is in threaded engagement with the threaded bore portion -17 of the extension while a piston 18 is slidably mounted in the bore of said extension. A control rod 19 fixedly con nected to said piston slidab ly extends through sleeve 16 and has a threaded end 20 in threaded engagement with button 21.

End portion 1 has the bore 13 thereof threaded at 22 while cylindrical wrench handle 24 has a threaded end portion 25 extending within bore 13 and being in threaded engagement wit-h threads 22. A set screw 23- extends through end portion 1 against handle end 2 5 retaining the same together.

An oil line bore 26 extends lengthwise of handle 24 while flange 27 extends parallel to, but spaced from handle 24. A screw 28 extends through flange 27 and pawl 29 into threaded engagement with said handle. Pawl 29 has a pair of divergent teeth 30 and 31 on one side and a series of recesses 32 on its opposite side. A plunger 34 backed by spring 35 and .slidably in recess 36 mates with one of said recesses 32 at a time to hold one or the other of said teeth 30 and 31 extending lengthwise of said handle as indicated for tooth 30 in FIG. 9. Tooth 31 can be moved forward upon pivoting pawl 29 about screw 28. 1

As shown in FIG. 6, handle 24 has an extension 37, of less width and with a curved toothed end 38. Forks 39 and 40 of cylindrical plunger 42 have extension 37 positioned therebetween while an axle 41. extends therethroughpivotally connecting said extension to said forks. Said plunger is of the same diameter as handle 24 and QB has an annular lateral flange 43 and a longitudinal square extension 44 beyond said flange. An oil line bore 46 extends through the length of plunger 42 including extension 44.

A housing 47 has a cylindrical recess 48 in which slides flange 43. A sleeve 49 in threaded engagement with the threaded open end portion 50 of recess 48 has plunger 42 slideably extending therethrough. A thrust bearing 45 is held against sleeve 49 by a coil spring 51 mounted on flange 43. Said housing also has a square recess 52 capable of receiving and mating with extension 44 as shown in FIG. 5. An oil line bore 53 extends frorn recess 52 to end 55 of a square bit 54 integral with said housing.

Housing 47 has an enlarged annular head 46 whose periphery has a series of teeth 57 providing a ratchet therearound for purpose to be hereinafter described.

Bit 54 has a side recess 58 in which is positioned a spring 59 and a ball 60 can only partially extend from recess 58 due to a restricted opening thereof. A conventional socket F can slide onto bit 54 and ball 60 which can only partially extend from recess 48 due to a restricted opening thereof. A conventional socket F can slide onto bit 54 and ball 60 will slide into a recess in the socket bore tending to receive said socket on said bit.

In the use of wrench C, handle 24 is inserted in handle end portion 1 and set screw 23 tightened onto handle 24 for retaining the same. A socket F for the size nut or bolt to be turned thereby is added onto bit 54. If the wrench is to be used as a speed wrench, the elements assume the position shown in FIGS. 1, 2 and 5. Also, if it is necessary to lubricate the nut or bolt to be turned, after placing socket F on the nut or bolt, compressing button 21 causes oil from handle bore 13 to be forced by piston 18 through oil line bores 26, 46 and 53 outwardly of bit bottom 55 onto the nut or bolt. By rotating handle A, wrench C is likewise turned through the mating of extension 44 in recess 52 and thus the rotation of socket F.

If it is desired to operate wrench C as a ratchet wrench the elements thereof are positioned as shown in FIGS. 4, 6, 7 and 9 by raising plunger 42 in bore 48 against spring 51 and pivoting handle 24 about pin 41 until pawl 29 faces ratchet teeth 57. Extension 44 is thus withdrawn from recess '52 and plunger 42 is free to rotate in housing 47. By oscillating handle A either tooth 30 or 31 engages a ratchet tooth 57 rotating housing 47 and socket F in the direction desired.

Handle 24 can be placed at angles by raising the same to the desired angle and letting spring 51 pull plunger 42 inwardly of bore 48 until teeth 38 engage the edge of sleeve 49 whereupon said handle will be held at the desired angle.

Raising plunger 42 and positioning handle 24 in line therewith as in FIG. 5 will permit spring 51 to return extension 44 to recess 52 and thus the elements can be again used as a speed wrench.

Wrench D has a handle 61 of an annular cross-sectional configuration capable of being inserted in handle end portion 1 and retained by set screw 23. Said handle 61 also has forks 62 and 63 with recess 64 therebetween as well as an oil line bore 65 extending the length thereof.

A pin 66 extends through forks 62 and 63 as well as the fiat head 67 of a cylindrical plunger 68, extending into recess 64 pivotally connecting handle 61 and plunger 68. A pair of stops 69 and 70 are fastened to opposite sides of plunger 68 by screws 71 and 7-2 respectively.

Housing 73 has a head 75 with a flat top 74, ratchet teeth 76 in the periphery thereof and a recess 77 capable of receiving forks 62 and 63. Further housing 76 has interior recess 78 in which is retained sleeve 79 by set screws 80. A coil spring 81 is positioned between sleeve -79 and stops 6970. An oil line bore 82 extends the length of plunger 68 including head 67.

A bit 8 3 is integral with housing 73 and has a square cross-sectional configuration and an oil line here extending from recess 78 to bottom 85 of said bit. Further said bit has a side recess 86 with a coil spring 87' and ball 88 therein and a restricted opening that only permits part of ball 88 to extend from said side recess for retaining a socket F on said bit.

Handle 61 has a lateral projection 89 with a recess 90 therein containing a spring 91 and plunger 92. A pawl 93 is pivotally mounted on screw 94 extending through said projection and has a series of recesses 95 for receiving plunger 92 as well as a pair of teeth 96 similar to pawl 29.

Handle 61 has a resilient hollow nipple 97 embedded within the end 98 and which nipple has bores 99 and 100 in line with oil line 65. Bore 100 is normally closed, but opens when oil is forced therethrough. Plunger head 67 has aresilient member 101 embedded therein and positioned for mating with nipple 97 when handle 61 is in line with head 67 as shown in dotted lines in FIG. 13. Said member -101 has a bore 102 in line with oil line 82 as well as nipple bore 100.

Oil line 26 similarly has a nipple 97 mating with a member 101 in the end of bore 46 in plunger 42 as shown in FIGS. 5 and 7.

Wrench D can be used as a speed wrench when positioned as in FIG. 12 or as a ratchet wrench when positioned as in FIG. 13 by pulling handle 61 and raising stops 69-70 against spring 81 until handle 61 can be pivoted about pin 66 and laid flat on the head top 74 with pawl 96 engaging ratchet teeth 76. However, handle 61 can be held at an angle to housing 73 by raising plunger 68 and engaging teeth 103 on the end of handle 61 with the edge of recess 77 where it will be held by spring 8 1.

Recess 77 is square for mating with forks 62 and 63 as shown in FIG. 14 whereby rotation of handle 61 will rotate housing 73. When said forks are out of said recess 77, plunger 68 is free to rotate in housing 73 and thus it is the movement of said pawl 96 on teeth 76 that rotates housing 7 3 when used as a ratchet wrench.

A further form of wrench E is shown in FIGS. 16 to 19, inclusive, which has a handle 103 also for use with handle A as with the previous forms of wrenches C and D. Handle 103 has a flattened end portion 104 with a curved end 105 and an oil line bore 106 extending the length of said handle 103 terminating in a nipple 97 embedded in end 105.

Handle end portion 104 is positioned between the forks 108 and 109 of a cap 110. A pin 107 extends through forks 108 and 109 and end 104, pivotally connecting handle 103 to cap 110.

Said cap 110 has a lateral recess 111 and an internally threaded bore 112 with set screws 113 extending thereto. A ratchet '114 is positioned within recess 1 11 and has a series of teeth 1'15 around the periphery thereof.

A tubular body 116 has an inturned annular flange 117 and a threaded periphery 118 in threaded engagement with cap threads 112. Flange 117 provides a square opening 117'.

A square plunger 119 slideably extends through opening 117 and has an annular portion 120 and square end portion 121 as well :as an enlarged end 122 also of a square cross-sectional configuration. A coil spring 123 is mounted between flange 117 and end 122.

Handle end portion 104 has a curved series of recesses 124 for receiving a spring pressed ball 125 in fork 108 to retain said handle at various angular positions when desired. Handle 103 has a lateral projection 126 in which is pivotally mounted a pawl 127 similar to pawl 29, engaged by a spring loaded plunger 128 and pivotal about pin 129 extending through projection 126 and said pawl.

Plunger end portion 121 has a spring loaded ball 130 similar to ball 60, in the side thereof so that a socket F can be retained on end portion 121.

Ratchet -1l14 has a square center opening 131 through which plunger end 122 is slideably positioned.

To use wrench E handle A receives handle 103 in end portion 1 and set screw 23 is fastened against handle 103 and socket F receives end portion on bit 121. With the elements positioned as in FIG. 18, handle A is rotated with handle 103 thereupon turning forks 109-109 and thus cap 110, body 116, plunger 119 and the socket F.

To use the wrench as at ratchet wrench, handle 103 is pivoted, as shown in FIG. 17, about pin 107 and curved end thereupon permits plunger head '122 to slide upwardly through round opening 132 until round portion 120 of said plunger is positioned in opening 117' due to spring 123 whereby said plunger is free to rotate in body 116. Pawl 127 then engages ratchet teeth 115 and by oscillating handle A, handle 103 will move the pawl teeth in engagement with ratchet 114 which turns plunger 119 and socket F due to head I122 mating with ratchet opening 131.

Pivoting handle 103 in line with plunger 119 causes curved end '105 to move said plunger inwardly until plunger 119 again mates with opening 117' whereupon the wrench can be used as a speed wrench.

FIG. 20 discloses a modified form of handle A which omits elements 8 to 11 and 15 to 21, inclusive, namely, the oil pump of FIGS. 1 and 10, and instead has an annular peripheral indentation 133 in which is seated a stop ring 134 and an annular stop protuberance 135 in bore 13 at end 5 of said handle.

A knob 136 having an interal bore .137 in which is positioned coil spring 138, is slideably mounted on end 5. Said knob has internal square recess 139 and larger recess 140. A plug 141 is in threaded engagement with threaded bore 7 of said end 5 and has a squared flange 142 capable of being seated in bore 139. A nut 143 fixedly connected to shaft 144 is shown in threaded engagement with plug 141 and rod 144 slideably extends through plug 141. A piston 146 is fixedly connected to one end of rod 144 and extends across bore \13 while a port extends through said rod and piston. Rod 144 has a threaded end 147 with threads opposite to those on nut 143, with nut 148 in threaded engagement therewith.

A coil spring 149 is positioned between piston 1147 and ring 150 seated on stop 135, tending to move piston 146 against plug 141.

In the use of the handle shown in FIG. 20, nut 148 is rotated in the proper direction to unscrew nut 143 from plug 141 releasing rod 144, which is pushed out by spring 149 so that it can be reciprocated whereupon piston 146 will draw air in through port 145 and force the air against the oil in reservoir B and out through passageway 26 or the like. Replacing nut 143 in plug 141 will hold the piston I146 in the position shown in FIG. 20.

Knob 136 is shown in FIG. '20 for unscrewing plug 141 from bore 7 or returning the same therein. For this purpose knob 136 is moved against spring 138 to the position shown whereby bore 139 which is of a square crosssectional configuration will mate with squared flange 142 and by rotating knob 136 will unscrew plug 141 from bore 7 or screw the same therein. Releasing knob 136 will allow spring 138 to push the same along end 5 until stopped by ring 134 and thus move .recess 139 from flange 142 so that said flange will be in recess 140 and thus not affected by rotation of the knob 136 at such times.

FIG. 21 is a cross-sectional view of a modified form of wrench having a housing 151 with an integral bit 142 which has a spring pressed ball 153 therein. Said housing has an annular recess 154 and a larger annular recess 155 with a side recess 156 in the wall defining recess 155. A smaller side recess 157 opens into recess 156.

A screw recess 158 opens into recess 156 and has a threaded portion.

Recess 155 has a threaded mouth 159 While a ratchet wheel 160 is seated in recess 155 below said threads. A stub axle 161 is seated in recess 154 and is integral with said ratchet wheel. A second stub axle 162 is also integral with said ratchet wheel and extends through ring 163 whose threaded periphery is in threaded engagement with mouth 159. Said axle 162 has a rounded end portion 164 and an oil line 165 extending through axles 162 and 161, and ratchet wheel 160 and is in line with oil line 166 extending through bit 152.

Ball and indent means 167 are provided on axle 162 and the bifurcated end 168 of a handle 170 similar to handle 61 and said handle also has an oil line 169, the length thereof.

A pin 171 extends through axle 162 and said bifurcated end 168 pivota-lly connecting said handle 170 to said axle 162.

A pawl 172 is positioned in recess 156 facing the notched periphery of ratchet Wheel 160 and has screw 173 in recess 158, extending therethrough pivotally supporting said ball. A spring 174 is located in recess 157 and pushes a ball 175 against indentations in said pawl;

In the use of the device of FIG. 21, handle 170 is connected to handle A of either FIG. 1 or FIG. 20 and positioned either as shown in FIG. 21 or said handle 170 is pivoted upright in line with axle 162 whereupon oil line 169 is in communication with oil line 165.

When handle 170 is in the position shown in FIG. 21 reciprocation thereof recip-rocates ratchet wheel 160 which engages pawl 172 and thereby rotates bit 152 in either direction. If handle 170 is pivoted upright it is then rotated about its axis to turn bit 152.

FIGS. 22 to 24 are directed to a further form of socket wrench and oiler and has a housing 176 with a bore 177 of a square cross-secti0nal configuration. A tube 178 is partially extending over the periphery of housing 176 and fastened thereto by screw 179. Said tube has a recess 180 in the top portion thereof.

A rod having an annular medial portion 181 and square end portions 182 and 183 slideably extends through housing bore 177 while end 183 is integral with ratchet wheel 184 facing recess 180, and extends laterally of bore 185 of said tube.

A coil spring 186 surrounds said rod between ratchet wheel 184 and housing 176.

An oil line 187 extends the length of said rod and axially of said ratchet Wheel with a resilient member 188 in one end thereof similar to member 101.

Tube 178 has a pair of spaced apart flat face forks 189 extending longitudinally thereof and a curved series of spring pressed balls 190 in the inner face of at least one of said forks.

A handle 191 has an oil line 192 extending the length thereof with a resilient nipple 193 in one end which nipple is normally closed.

A pin 194 extends through said handle 191 and forks 189 pivotally connecting the same. Said handle also has a curved series of indentations facing balls 190 to hold handle 191 in angular positions. Said handle between said forks is of rectangular cross-section slideably fitting between said forks.

A ratchet 195 is pivotally supported on screw 196 extending therethrough and in threaded engagement with handle 191. A spring pressed wedge 197 engages ratchet 195 in the manner of elements 30 to 35 inclusive of FIG. 9, for engaging said wedge with ratchet wheel 184 through recess 180.

In the use of the wrench and oiler of FIGS. 22 to 24 with the elements as shown, handle 191 is reciprocated laterally with ratchet 195 engaging the teeth on ratchet wheel 184 rotating end 182 which provides a bit.

Moving handle 191 about pin 194 to a position in line with rod 181 pushes ratchet Wheel 184 against spring 186 until end 183 mates with bore 177 and nipple 193 abuts member 188 placing oil lines 192 and 187 in communication.

Thereupon giving handle 191 and axial rotation will rotate bit 182 due to the connection of end 183 with housing 17 6 '7 Oil can also be forced by either handle A attached to handle 191 by pumps or 146.
